patch for fix a crash bug
I found a crash bug in mod_proxy_uwsgi.c with h2 protocol.
Accoding to core dump, a crash point was in following line#178 in
mod_proxy_uwsgi.c:
>> headerlen += 2 + strlen(env[j].key) + 2 + strlen(env[j].val);
I confirmed value of env[j] like following:
(lldb) p env[j].key
(char *const) $4 = 0x00000008015d5e9f "H2_STREAM_ID"
(lldb) p env[j].val
(char *const) $3 = 0x0000000000000000 <no value available>
So I consider that env[j].val is nullable.
Please apply attached my patch.
